| Abstract: The extraction equilibrium of zinc(Ⅱ)from hydrochloric acid solution by primary amine N1923 has been studied. It was found that the extraction mechanism of zinc(Ⅱ)varies with the equeous acidities. It belongs to extraction mechanism of solvated complex and the composition of extracted complex is(RNH2)2 ZnCl2 in which nitrogen atom is coordinated to zinc ion at pH>2. Otherwise, An adduc reaction between RNH3C1 and ZnC12 produced the compound(RNH3)3[ZnC5] at high concentration of HCl. These reactions are as follows. 2RNH2(o)+ZnCl2⇔(RNH2)2ZnCl2(o) (RNH3Cl)3(o)+ZnCl2⇔(RNH3)3[ZnCl5](o) The eguilibrium constants and thermodynamic functions of both reactions were measured. The IR and NMR spectra of the extracted species were investigated. |
